Should an automatic car be started in P gear or N gear?

[VanMatthew]

Automatic transmission cars should be started in N gear. Starting in P gear may exert slight impact force on the parking gear. When shifting from P gear to D gear after ignition, the transmission passes through R gear, which generates a reverse impact force that causes minor damage to the transmission. Below are relevant introductions about automatic transmission shifting methods: 1. First power on, press the brake to shift to N gear, ignite, then shift to D gear to start. Most car computer systems default to requiring P gear to start the engine, so it is recommended to use P gear for ignition for greater safety. 2. As long as you don't stay in R gear, the transmission won't perform shifting actions. 3. Modern automatic transmissions don't rely on the gear lever directly driving the transmission to shift gears, but rather on the transmission control system. After receiving the gear signal, the transmission control system calculates and then makes the shifting decision.
